THERMOMETER.

Application iled February 14,1922. Serial No. 536,478.

' and a structure for supporting `the thermometer, an object of the invention being to provide a thermometer which may be attached to a window frame, and be visible both from the interior and exterior of the window and also to provide a supporting structure for the thermometer which is designed to permit the supporting of the thermometer in an extended position or in a folded vposition close to the frame or support to which it is attached.

Other objects of the invention will appear in the following detailed description taken in connection with the accompanying drawings wherein:

Fig. 1 is a perspective view of the improved thermometer showing it attached to a support.

Fig. 2 is a front elevation of the thermometer.

Fig. 3 is a detail side elevation illustrating one of the thermometer supports.

Fig. 4 is a detail cross section taken on the line 4 4 of Fig. 2.

Referring more particularly to the drawings, the improved thermometer comprises a rectangular frame 1 constructed of any suitable material and having a transparent panel 2 supported therein. As clearly shown in Fig. 4 of the drawings, the frame 1 projects beyond the sides of the transparent panel 2 sufficiently to form a guard for the transparent panel. The transparent panel 2 is provided with a longitudinally extendingv centrally disposed slot 3 terminating in the rounded enlargement 4 near the lower end of the panel, which slot and enlargement receive the tube 5 having the customary bulb 6 at its lower end and in which tube and bulb a mercury or analogous thermostatic fluid is placed for movement in the tube and cooperation withthe graduations 7 to determine the thermo degree of the atmosphere surrounding the thermometer. formed of glass is graduated upon its opposite surfaces along opposite sides ofthe slot 3 as shown in Fig. 2 of the drawings so as to permit the reading of the thermometer from either side. If it is so desired a holey 8 may be provided in the transparent panel to permit the thermometer to be suspended from a hook or analogous support.

Supporting arms 10 are pivotally connected as shown at 11 to one edge of the thermometer structure and have their free ends provided with openings 12 to receive screws,

nails, or the like for attaching the supports to a supporting structure such as a window frame A, or the like. The pivotal connection of the supports 10 with the frame 1 will permit the thermometer structure to be supported in an extended position as shown in Fig. 1 of the drawings, or in a folded position close against the window frame by the movement of the supports alongside and in flatwise engagement with the edge of the frame 1 to which they are attached as shown in dotted lines in Fig. 3 of the drawings.

It is to be understood, of course, that the tube 5 is supported in its proper position in the slot 3 by the usual form of straps 14.

It is to be understood that the invention may be constructed in other manners and the parts associated in other relations and, therefore, I do not desire to be limited in any manner except as set forth in the claims hereunto appended.

Having thus described my invention what I claim is:

1. In a thermometer, a frame, a transparent panel carried by said frame and provided with a longitudinal slot, an indicating tube supported within said slot, said plate being graduated on each side surface along one edge of said slot, the graduations on one side ofthe plate being at the opposite side of the slot from the graduations on the opposite side of the plate.

2. In a thermometer, a frame, a transparent panel carried by said frame and provided with a vlongitudinal slot, a thermometric material containing tube supported within said slot, said plate being graduated on each side surface along one edge of said slot, the graduations on one side of the plate The plate 2, which is preferablyl being at the opposite side of the elet from the giacluations on the opposite side of the plate, and supporting arms pivotally connectecl to said frame at one edge of the plate 5 and adapted for attachment to a Support.

3. A thermometer comprising a rectangular frame, a rectangular panel centrally Supported Within the frame and having a slot, and a heat indicating tube supported Within the slot, said frame extending a predeter 10 mined distance to opposite sides of the tube.

In testimony whereof I affix my signature.
